WIRE OR BICYCLE SPOKE STRAIGHTENER.

SPECIFICATION forming part of Letters Patent No. 497,116, dated May 9, 1893.

Application filed June 17, 1892. Serial No. 487,088. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM G. BROWN, a citizen of the United States, residing at Danville, in the county of Montour and State of Pennsylvania, have invented a new and useful device or tool which I have termed a Wire or Bicycle Spoke Straightener, of which the following is a specification.

This invention relates to an improvement in wire straighteners, and more particularly to that class employed in straightening bent or kinked spokes of bicycle wheels.

The object of the invention is to produce a wire straightener which shall be simple of construction, of the highest efficiency and durability in use, and which maybe manipulated by the ordinary bicycle-rider.

With these objects in view, the invention consists in the novel details of construction of a wire straightener as will be hereinafter fully described and claimed.

In the accompanying drawings forming a part of this specification, and in which like letters of reference indicate corresponding parts Figure 1, is a plan View of the device. Fig. 2, is an edge view of the same.

Referring to the drawings, A designates the stationary handle and B the movable handle. The outer end of handle A is bifurcated or formed into a yoke 0, one member D of the yoke being arranged at some distance to one side of an imaginary line drawn longitudinally through the center of handle A, while the other member E is arranged but slightly to one side of the said line. The function of this arrangement Will appear later on. Each of the members D, E, is provided at its outer shoulder or lug 11 through which passes a rivet or bolt I to secure the said handle to the member D of the yoke. From the pivotal point, the metal of the handle projects outward and terminates at the end with a cam-shaped clamping-j aw J, which, when the handles are closed, occupies a position midway of the two members D, E, and projects beyond the inner wall of the lugs F. The face of the clamping-jaw is also grooved as at K for the same purpose as stated in connection with the lugs F.

In employing the device, the handles are opened and the lugs brought into contact with the wire or spoke, one on each side of the kink or bend. The handle B is now forced inward, and the cam-face by being brought into engagement with the irregularity in the wire or spoke straightens or smooths it out in an obvious manner.

Having thus described my invention,'what I claim is t 1. In a bicycle spoke-straightener, the combination of a stationary handle having ayoke at one end,the members of which are arranged one at a slight distance to one side of an imaginary line drawn through the center of the handle, and the other at a considerable distance to the opposite side of the said line, a single lug carried by each member of the yoke and extending at right angles thereto, and a movable handle pivoted to one of the members eccentrically to the lug, and having an integral cam-projection extending at an angle to the movable handle and adapted to co act with the lugs for straightening the wire.

2. In a bicycle spoke-straightener, the combination of a stationary handle havingayoke at one end, the members of which arearranged one at a slight distance to one side of an imaginaryline drawn through the center of the handle, and the other at a considerable distance to the opposite side of the said line, a single grooved-face lug carried by each member and extending at right angles thereto and a movable handle pivoted to one of the members eccentrically to the lugs and having an integral cam-projection extending at an angle to the movable handle, and provided on its face with a groove, substantially as and for the purposes specified.
